Food Vacuum Freeze Dryer



  The vacuum freeze drying equipment is an advanced method for the material dewatering.It freezes the moisture material in the low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensing way so as to dewater and dry the material.

  Being processed by the vacuum freeze dryer, the physical, chemical and biological states of the material are basically unchanged. Freeze drying maintains the original smell and flavor of the product.

  Freeze Dried product is convenient to store and transport:Dried material low moisture content, that is light weight. Easy to store for a long time.


Freeze dryer is suitablefor food industry, pharmaceutical industry, chemical industry etc. Food vacuum freeze dryer is used for freeze-dried fruits, meat, vegetables and other foods.
